PURPOSE:To prevent the decrease of hot-water reserving amount of a heat collector due to the reason of circulation of water by a method wherein a vessel, securing a hot-water reserving volume, is provided with a partitioning along the inner wall of the lower end of the vessel to form a flow path along the inner wall. CONSTITUTION:The heat collector 3 is accommodated in a housing 4 and a transparent plate 5 is disposed on the upper surface of the housing. The transparent plate 5 forms an air layer 6 between the heat collector 3. The L-shaped partitioning 10 is provided along the inner wall of the lower end section 9 of the vessel 1, securing the hot-water reserving volume, in order to form the flow path 11 along the inner wall. Here, the partitioning 10 is not limited to the L- shape and it may be a simple flow path along the end face of a tubular body 2 constituting the vessel 1. An ascending stream from the bottom surface of the vessel 1 toward a heat collecting surface is generated in the flow path 11 and, accordingly, high temperature hot-water may be obtained at a place below a horizontal line defined by the lower rim of the heat collector. |
